这是一个示例SVG图像，我需要将背景颜色从当前白色更改为透明（或黑色）。
到目前为止，我只能改变前景色。

试图修改pagecolor但没有成功。
我怎么能这样做，可能不使用CSS？

Inkscape往往会产生非常臃肿的文件。这是一个清理版本：
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 90 90">
<defs>
<mask id="chain">
<rect x="4" y="28" width="34" height="34" fill="black" stroke="white" stroke-width="7" rx="7" />
<rect x="52" y="28" width="34" height="34" fill="black" stroke="white" stroke-width="7" rx="7" />
<rect x="21" y="39" width="48" height="12" fill="white" stroke="black" stroke-width="4" />
</mask>
</defs>
<!-- Uncomment this for manual background -->
<!--rect fill="#000" width="90" height="90" /-->
<rect fill="#ff0" width="90" height="90" mask="url(#chain)" />
</svg>
你会注意到，这不仅比你的文件小得多，它也更容易看到发生了什么：我使用两个圆角正方形和一个矩形的链接，使用一个掩码来剪辑形状。然后，使用形状作为遮罩来填充颜色，以获得结果。
没有定义背景颜色。如果用作图像文件，它将透明显示其背后的任何背景。或者，您可以取消注释指示的行以强制显示图标背景。
